func Int() int
Int returns a non-negative pseudo-random int.
func Int63nRange(min, max int64) int64
IntnRange generates an int64 integer in range [min,max). By design this should panic if input is invalid, <= 0.
func Intn(max int) int
Intn generates an integer in range [0,max). By design this should panic if input is invalid, <= 0.
func IntnRange(min, max int) int
IntnRange generates an integer in range [min,max). By design this should panic if input is invalid, <= 0.
func Perm(n int) []int
Perm returns, as a slice of n ints, a pseudo-random permutation of the integers [0,n) from the default Source.
func SafeEncodeString(s string) string
SafeEncodeString encodes s using the same characters as rand.String. This reduces the chances of bad words and ensures that strings generated from hash functions appear consistent throughout the API.
func Seed(seed int64)
Seed seeds the rng with the provided seed.
func String(n int) string
String generates a random alphanumeric string, without vowels, which is n characters long. This will panic if n is less than zero. How the random string is created: - we generate random int63's - from each int63, we are extracting multiple random letters by bit-shifting and masking - if some index is out of range of alphanums we neglect it (unlikely to happen multiple times in a row)
